Description
6~!753 Cette invention concerne un Eer~ir et, plus particuli~re~ent, un fermoir miniature tel qu'utilis pour attacher dos cha~n~ttes servant au port de bijou~, Il est bien connu en bijouterie d'attacher las d-ux bouts d'une cha~nette port~e ~utour du cou ou du bras au moyen d'Qn fermoir. ~b tels`fermoirs s~nt aussi utiliq~s pour attacher des chalnettes de s6curit~ aux bijoux.
Le fermoir le plus connu commerci~le~ent est cclui en forme d'anneau creux dans lequel est mont~ un plong3ur qui glisse ~ ;
l'intérieur de l'anne~u et se referme dDns un~ extr~mit~ d'~nnoæu au moyen d'un ressort, qui est au88i mont6 dans l'anneau. Ce type de fermoir a cep`endant deo désavatangas maj~urs. Par ~xempla, le plongsur ~t le ressort, qui sont montés ~ l'int6rieur de l'anneau, ne ~ont pas suf~isamment v~ntil~s at se corrodent facilemsnt du ~ l'hu~idit~ de 1~ peDu, L'anneau peut aU8Ji ~tre , facilement apl~ti ou tordu, Il en r6suLte que le plongeur blo~u~
et le fermoir reste ouvert ou ~ moiti~ Eer~é, ce qui peut occ~-si~nner la perte d'un bijou d~ v~leur.
Il existe aUcai un autre type de fermoir en ~orme de pinc~, dont la m~choire est form~e de pluRieur~ paire~ de dents qui se chavauchent pour encercler particlle~ent l'anneau ~ l'extr~mité
de la cha~nette, L'anne~u de la cha~nette peut fàcilement s'accro-cher ~ une seula p~ire de dents et, si une trop forte t~n~io~ est appliqu~e sur la cha~nettc, ladite paire de den~s p~ut ca~æ~r~
Le but de l'invention est donc de pr~voir un fer~oir qui aat completemant s~curitaire et dont le~ compo6antes sont blon exposéas ~ l'alr afin de ne pa3 se corroder facile~ent.
Le fermoir~elon l'invention comporte un pr~iar 61~ent ayant un corps principal et une m~ohoire en forma do crochet reli~e int~grale~ant au corps principal du premier ~l~m-nt, at un deuxieme ~lément ~yant un corps princip~l 6 ~! 753 This invention relates to an Eer ~ ir and, more particularly, a miniature clasp as used to attach back cha ~ n ~ ttes for wearing jewelry ~, It is well known in jewelry to tie the two ends a cha ~ clear port ~ e ~ around the neck or arm by means of Qn clasp. ~ b such clasps are also useful for attaching jewelry security chains.
The most famous clasp commerci ~ the ~ ent is cclui in shape hollow ring in which is mounted ~ a plunger which slides ~;
inside the year ~ u and closes in a ~ extr ~ mit ~ d '~ nnoæu by means of a spring, which is also mounted in the ring. This guy of clasp to however two major disavatangas. By ~ xempla, the plunge ~ t the spring, which are mounted ~ the interior of the ring, have not suf ~ ciently v ~ ntil ~ s at corrodent facilemsnt of ~ the hu ~ idit ~ of 1 ~ peDu, The ring can auU8Ji ~ be, easily flattened or twisted, it follows that the diver blo ~ u ~
and the clasp remains open or ~ half ~ Eer ~ é, which can occ ~ -if ~ nner the loss of a jewel d ~ v ~ their.
There is another type of clasp in ~ pinc elm ~, whose ch ~ is formed of several ~ pair ~ of teeth which capsize to encircle particlle ~ ent the ring ~ the extremity of the net chain, The year ~ of the net chain can easily increase expensive ~ only one p ~ ire of teeth and, if too strong t ~ n ~ io ~ is applied to the chain, said pair of den ~ sp ~ ut ca ~ æ ~ r ~
The object of the invention is therefore to pr ~ see an iron ~ oir which completely safe and whose components are white exposed ~ the alr so that pa3 does not corrode easily ~ ent.
The clasp ~ elon the invention comprises a pr ~ iar 61 ~ ent having a main body and a hook shape connected ~ integral ~ ant ~ to the main body of the first ~ l ~ m-nt, at a second ~ element ~ with a main body ~ l

Les ma^~hoire3 du premier ~t du deuxi~me ~l~ment sont effil~e6 l'une ~ gauche et l'autr~ ~ droite de fa~on ~ pouvoir se chevaucher ~utuell~ent. De~ Doy9n~ sont prévus pour pivoter les corps du premier et du deuxi~e ~l~ment l'un par r~pport a l'~utre, de fa~on ~ c~ que les surfac~Y effil~es des ma~choire~ forment des surface~ d~ contact. Un re~sort ~st prvu pour forcer les mSchoiras du pre~ier et du deuxi~mo ~l~m3nts ~ se mouvoir l'une vers l'autre.
La partie intérieure du crochet de chacune des m~choires a un rayon de courbure correspondant au rayon de courbure d'un anneau norm~lement utili~ ~ l'e~tr~mité de cha~hette~, et la largeur de chacune des m~choiras est suffi~ante pour recouvrir une partie ~ubstantielle de la circonf~rence de l'~nneau pour emp~che~ 1A d~formation de l'anneau ou le bri8 des ~choire8 qu~nd une tension trop forte est appliqu6e fiur la cha~nette et égalem~nt pour emp~chor l'usure de l'anneau.
La cavité formée par le crochet des machoires ast aussi telle que le crochet recouvre de~ surfacos oppo8~20 de l'anneau en position tendue de la eh~nette ~t ain3i ~mp~che l'ouvcrture du fer~oir dan-~ cette po~ition, ce qui rend le fermoir tr~s s~curitaire.

extr~mit~ un crochet 24. Le corps principal de chacun de~
~léments 10 et la est muni de jambQs 26 ou 28 et a donc une se~tion transversale sn for~e d~ U. Les jambe3 26 du corp~
principal 12 chevauchent le~ ismbes 28 du corpa principal 20, l'une a l'int~ricur et l'autre a l'exterieur, com~e illustré à
la figure 5 des densin~. Une tige 30 traver~e les ~amb~a des deux bl~ments et sert do pivat au fermoir. L88 ~achoireo des ~ Hnt3 flOnt effil~ea, l'une à gaurh~ ot l'autre à droits, de fason à ce qu'slles puissent ~e chevaucher et former de~ aurface3 de contact ~2 dana un plan inclin~ par rapport a l~axe de 1~1 tige 3D. Un ressort 34 est monte sur la tige 30 et furce lea machoires à AD r~ermer ~ur leurs 8ur~acfl~ de contact 32. Le res~lor~t eot en forme d0 apirale et est ins~r~ entra un~ ~ambe 26 et une ~ambe 28 deo ~l~nent~ 10 et l~ pour empêcher 1~ ~ambe de gli~s~lr lat~ralement eur la tige 30.
Il est à noter que les mâchoires 14 et 22 sontef~ e~
aPin qu'an position ferm~e et de chev~uchQm~nt~ la ~om~ ds l~ur~

Finalement, la largeur de ch~cune de~ mRchoire~ 14 et 22 e~t telle qua le~ mschoires recouurent une partle sub~tanti~lle de l'~nneau de la cha;nette, ce qui ampêche la déformation de l'an-neau de~ m~choires, m8me 3i une tension considérAble eat subie par la chaine~te, en sa r~ppelant que le8 crochsts sont con~t1tués pr~f~rablement d~un~m~tal pr~cieux malléable, tel qUB l~or, ~t qUe la portion interm~diaire de cheque crochet e~t plus ~paicse que la pointe dudit crochet.
La cavit~ Por~ée par le3 crochets Permés 16 et 24 est -~
de dimension telle que l'annesu est encerclé par le crochet lor3que la cha~nette est tendue. De c0tte f~on, le ~ermnlr ne peut s'ouvrlr parce que las deux crochets 16 st 24 recouvrent des surPace~ oppos~es de J'an~eau et ainsi empêchent le ~ermoir de ~ouvrir. Pour ouvrir le fermoir, il f~ut poua~er l~anneau hor~ des cevit~ formées psr - 4a -les crochets 16 et 24 et ainBi d~bloquèr le f~rmoir.
Les el~ents 10 et 18 sont munis de pattes 36 et 38 perm~ttnnt l'ouverture du fermoir pour d~g~ger l'nnneau, comme illustr6 aux figure~ 2 et 3. La patte 38 est plus longue que la p~tte 36 pour y permettre la fixation d'un nnneau 40 servant ~ rolier le fermoir ~ l'autre extr~mit6 de la cha~netts.qan~ g~ner le ~ouvement de la patte 36. La patta 36 est munie d'une rainure 42 pour y in~rer l'ongle d'un doigt, de faScon ~ f~ciliter l'ouverture du fermoir.
Bien que l'invention ait ~t~ d~crite en se r~f~r~nt ~ une réalisation p~rticuli~re, il e~t bien ent~ndu qu~ des variantes sont aussi envisag~es dans le cadre des revendicatien~ qui suivent.

2'~ ~ 3 DIUULGATION SUPPLEMENTAIRE
Ceci est une divulgation suppl~mentaire suits l'invention d~crite ci-haut at intitules "Fermoir"~
Il s'agit d'un,s amélioration apport~e aux crochets 16 et 24 du fermoir. TB1S qulillustr~s dans 1BS dessins dls la divul-gation principale9 ces crochets 16 et 24 ont chacun un bout int~leur asssz pointu. Cette construction particuli~re est un désavantage car il est nécessaire de pousser l'anneau hors des cavité~ ~ormées par les crochets vers le~ pattes 36 et 38 pour fermer le ~ermoirO
Le but de la divulgation supplémentaire est donc de pr~voir un fermoir tel que d~crit ci-haut qui s0 ~ermfl automatique-ment ean~ auoir ~ deplacer l'anneau dls3~ retenu dans l'un des orochats.
La realieation am~liorée ~era décrite ~ titre d'exemple en sa réferant au dessin supplém0nta.ire~ dans lequel~

The purpose of the additional disclosure is therefore to pr ~ see a clasp as described above which s0 ~ ermfl automatic-ment ean ~ auoir ~ move the ring dls3 ~ retained in one of orochats.
